Do you have kids at home? If so, then your carpets are prone to accidental spills from milk, juice, ink and other liquids, causing stains and spots that would be difficult to remove. Your kids also like eating cookies, chips and other junk food which usually end up on your carpets. How about pets? Your four-legged furry friend sheds fur and love playing in the backyard and may hurriedly run inside with dirt and mud on their paws. Pet dander and outdoor debris will get transferred to your floor coverings.
